一般說明

甘油是一种无味无色并具有甜味的液体，在自然状态下具有黏性。它可以是自然存在的，也能衍生自石油化工原料。甘油具有十分广泛的应用，是自然中最具价值以及多功能性的化学物质之一。它可用作润肤剂、溶剂、甜味剂用于药物配方、化妆品、食品和化妆品中。它非常稳定且非常易于在常温下进行储存；它也没有刺激性，对环境没有不良影响。[1][2]

應用

甘油可用作：
  • 免疫荧光封固剂成分
  • 结核分枝杆菌和鸟分枝杆菌细胞培养过程中的补充剂；[2]
  • 酶生物燃料电池设计过程中的燃料；[3]
  • 含有4-HCCA和3-氨基­喹啉的液体复合基质，可用于分析中性和酸性聚糖；[4][5]
  • 进行快原子轰击电离质谱的基质；[4][5]
甘油可用作MALDI（基质辅助激光解吸/电离质谱）定量分析研究的液体基质。[6]

生化／生理作用

甘油天然具有是吸湿性，并因其三个亲水性醇羟基而可溶于水。它可形成分子间及分子内的氢键，使其成为一种非常灵活的分子。 甘油的生理作用与细胞介导的免疫、IgG生成的提高以及增加的组胺释放相关。[1][2]

特點和優勢

本品已针对是否存在核酸酶和蛋白酶进行了分析。

Questions

1–7 of 7 Questions  

  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  3. Is there any benefits or harm if we store this glycerol product in 4C or -20C rather than in RT?

    1 answer

    1. The failure modes of this product are not tested. It could be okay if stored under the described conditions, but it would no longer be guaranteed under the standard warranty if the storage conditions are not adhered to. The customer would need to determine the effectiveness of the chemical after cold storage.
